The Ideal Mixing Departure in Vector Meson Physics

Abstract

In this work we study the departure for the ideal $\varphi -\omega$ mixing angle in the frame of the Nambu-Jona-Lasinio model. We have shown that in that context, the flavour symmetry breaking is unable to produce the shifting in the mixing angle. We introduce a nonet symmetry breaking in the neutral vector sector to regulate the non-strange content of the $\varphi$ meson. The phenomenon is well reproduced by our proposal.
